Two Ball Flipper- a K'nex Ball Machine Element

About: I like to build with K'nex and Lego.

I call this element Two Ball Flipper because when the second ball goes in, the balls flip over each other. Note: A ball must come in the top entrance track, and then another ball must come in the lower entrance track for the element to work properly.

Here is the parts list:

Rods:

Green: 68

White: 6

Blue: 38

Yellow: 33

Red: 50

Gray: 14

TOTAL RODS: 209

Connectors:

Dark Gray: 16

Orange: 24

Red: 22

Green: 10

Purple: 60

Yellow: 46

Blue: 12

TOTAL CONNECTORS: 190

Other:

Blue Spacer: 60

Gray Spacer: 36

    looks nice! I like multi ball elements a lot :). Is it possible to remodel the final track, so the element has fewer height loss?
